To all whom it may concern:

Bert known that L-PHILANDER H. STAND- I'sH, a citizen of the UnitedStates of'America, residing at Cleveland, in the county of,

able others skilled in the art to which it per tains to make and use thesame.

This invention relates to improvements in ap aratus for 'carrying andheatin chainlin .blanks, ring-blanks and other b anks.or

articles preparatory to welding or otherwise operating on them. i

The primary object of this invention is to improve the apparatusillustrated and described in United States Letters Patent No. 502,594granted to me August 1, 1893, to the end of rendering the apparatus moresimple and inexpensive and otherwise advantageous in construction andmore convenient, accurate and reliable in operation.

Another object is to enable and facilitate accuracy in the relativeadjustment of the blank-carrier and blank-heating means.

Another object is to render the blank carrier capable of being shiftedout of the way of the blank-heating means to avoid exposure of theblank-carrier to the heat of the blank-heating means when the blankcarrier is not being operated. f With these objects in view, and to theend of realizing other advantages hereinafter appearing, this inventionconsists in certain features of construction, and combinations of partshereinafter described, pointed out in the claims and illustrated in theaccom- -panying drawings.

In the said drawings, Figure 1 is a top plan of apparatus embodying myinvention. 1g. 2 1s a sideelevation of the same. Fig.

.3 is a vertical section on line 3 -3, Fi

the

lookingin the direction indicated by arrow. Fig. 4 is a vertical sectionin detail on line 44, Fig. 1, lookin in the direction indicated by thearrow. zontal section on line 5-5, Fig. 2, downwardly.

Referrin to the drawings, A indicates the casingof t e furnace which isrendered stationary in any approved manner, beingpreflooking erablmounted on and secured to standards a which (see Figs. 2 and 3) areprovided at ig. 5 isa horitheir lower ends with laterally projectingflanges a into and through which are screwe set-screws e which rest upona base or foundation f and render the furnace or heating meansadjustable vertically, and nuts e are mounted on the screwse to lock thesetscrews in the desired adjustment.

B indicates the combustion or heating chamber of the' furnace, whichchamber is arranged centrally of the casing A, as shown in Figs. 1 and3.

C represents an air-pipe or flue that discharges into the chamber Bthrough. an aperture b formed in one of the end walls of the saidchamber, as shown in dotted lines Fig. 1.

D (see Fig. 1) represents a p1 e arranged to conduct gas, oil, or otherfluir used as fuel, to the chamber B. The pipe D is arranged centrallyof the air-flue C and discharges within and centrally of the aperture band such a distance from the discharging end of the said aperture thatthe gas or substitute and the air will commingle before being dischargedinto the chamber B of the furnace.

G represents a shaft which is arranged vertically externally and at oneside of and a suitable distance from the furnace centrally between theends of the furnace. The shaft G forms a portion and is arrangedcentrally of the carrier employed in conveying the blanks or articles tobe heated through the heating chamber B of the furnace, and the saidchamber is arranged concentrically of the said shaft and consequentlyconcentrically of the blank-carrier, and the combustible mixture whichconstitutes the fuel to be discharged and burned within the said chamberis introduced into .the chamber through the aperture 6 as alreadyindicated.

The heating chamber B extends to the top surface of the furnace but theupper portion B of the said chamber (see Figs. 1 and 3) is narrower thanthe central and lower portions of the chamber so as to concentrate theheat at the point Where the blanks or articles to be heated aresuspended and to prevent. the heat from blowing or shooting upwardly outof the furnace. It will be observed therefore that the blanks orarticlesto be heated are suspended and heated during the operation ofthe apparatus within the upper'and narrower portion B of the chamber Band preferably the said u pcr and narrower portion of the said chamfieris just wide enough to freely accommodate the sus ension therein of theblanks or articles to be eated.

The shaft G is supported as will hereinafter appear, and theblank-carrier also comprises a wheel H which is o eratively mounted onthe upper portion of t e shaft a suitable distance above the furnace.The wheel H has a circumferentially extendin annular rim 7:. and isprovided with blan -holders I by which the blanks or articles to beheated are suspended within the u per portion B of the heating chamberB. referably the rim h is provided in its upper side with grooves orrecesses h equidlstantly spaced circumferentially of the wheelH andarranged radially of the said Wheel, and each blank-holder 1 preferablyconsists of abar or rod which has a horizontally arranged innerendt-iportion 7 engaging a recess h. The inner en -portions 7 of theblank-holders I extend through the recesses h and are conse uentlyarranged radiall of the wheel 'H. e blank-holders I are etachablysecured to the rim h as will hereinafter appear. It will be observedtherefore thatthe blank-holders I are supported from and arrangedradially relative.

to the shaft G and s aced e uidistantly circumferentially of t e saidshaft. Each blank holder I extends laterally and .outwardly anddownwardly from the wheelrim h anditerminates' at its outer and lowerend in a hook 8 ada ted to receive a blank or article to be carriethrough the upper portion B .of the heating chamber B and suspended andheated within the said portion of the said chamber.

The means for detachably securing the blank-holders I to thewheel-rim hpreferably comprise clamping plates or members J which rest u on theinner'ehd-portions 7 of the blank-hol ers and are secured to the saidwheel-rim by suitabl a plied screws J. Obviously the side wal s of t erecesses 72/ are instrumental in preventing displacement of theblank-holders I circumferentially of the blank-carrier.

The arrangement of the heating chamber of the furnace and theblank-carrier which, as already indicated, comprises the shaft G, wheelH, holders I, and the means for securing the said holders in place uponthe wheel, is such that a blank hung u on the outer and hook-forming endof a holr er I externally of the furnace is during the rotation of thecarrier, when the latter is in its normal and operative position asshown, conveyed into and through the up er portion B of the heatinchamber of t e furnace so as to be pro er y heated in its passa ethrough the sai chamber.' In Fig. 3 a chain-link-blank a is showndepending from a blank-holder I into the said upper portion B of thesaid chamber.

The blank-carrier is intermittently actuated as will hereinafter appear,and the end walls of the upperportion B of the heating chamber arerecessed in the top thereof, 'as at 'zonta y arranged arm 12 b Figs. 1and 2, to accommodate the passage or travel of a laden blank-holder Iinto and out of the chamber.

The inner horizontally arranged end-portions 7 of the blank-holders Iproject a suitable distance beyond the external peripheral surface ofthe wheel-rim h and operate as the teeth of aratchet-wheel, beingpreferably cylindrical in cross section, as shown in Fig. 4, or at leastrounded on top to facilitate the o erative engagementjtherewith by asuita ly applied and suitably operated pawl P whlch is preferably rigidwithone end of a rod or pitman p which is suitably pivoted at its otherend, as at p,- to the crank t of a suitably supported crank-shaft Twhich is operatively provided witha suitably driven pulley or drivingwheel T which during the o erat'ion of the apparatus is rotated in theirection indicated by the arrow placed thereon in Fig. 2. An arm at isshown turn ably embracing the shaft G and resting upon the hub of thewheel H. The arm a: extends laterally from the shaft, G to the pawl Pwhichls connected with the said arm by a universal joint, as, forinstance, by a balland-socket joint having its ball a" formed on -theouter end of the arm and engaging a correspondingly shaped socket formedin the pawl whic is made in halves or sections to accommodate theprovision of the said joint, which sections are detachably secured together by suitably applied screws P. I A collar yembracing and fixed tothe shaft G above-the awl-connecting arm as prevents upward disp acementof the said arm.

The shaft G has lateral bearing intwo vertically arranged boxes 10 and10 which are spaced vertically and formed on and being portions of abracket K which is hinged or pivoted vertically, as at K, to lugs Aformed on the furnace-casin A at the adjacent end of thefurnace. It Wlllbe observed therefore that the bracket K is capable of being swunglaterally in a horizontal plane and away from the furnace-casing whenthe, blank-carrier is elevated to the extent required to raise theblank-holders I out of and above the furnace, but. the bracket isnormally locked in its normal position b means comprisin a bolt R, nutsR and 2 and a horirojectingfrom and formed on the bracket The bolt R isarranged horizontally and extends loosely through the bracket-arm 12,being pivoted vertically at one end, as at r (see'Flgs. 3 and 5) to alug A formed on the furnace-casing, and the nuts R and R? are mounted onthe said bolt at opposite sides respectively of the said arm;

A collar G is mounted on and fixed to the lower end of the shaft G asuitable distance below the bracket K, which collar is borne by a leverM which surrounds the said collar and is provided with a slot M largeenough in dimensions to accommodate the location -of the said collarwithout interfering with the operation of the lever, and the slottedcollarsurrounding portionof the lever is pivoted 5 horizontally at thesides of the lever to the collar by suitably applied pivot-formingscrews 0. The lever M is fulcrumecl-horizontally at one end, as at m,(see Fig. 2) to a bar or link L which is pivoted at its upper end as atZ, to the lower portion of the bracket. The lever M extends under thearm 12 of the bracket K. The last-mentioned pivot, the pivots O and thefulcrum m are parallel. It will be observed therefore 5 that the lever Mis capable of bein swung in a vertical plane, and that the sha t G ofthe blank-carrier, being borne by the lever, is raised or loweredaccording as they lever is swung upwardly or downwardly. In the normaland operative position of the blank-- carrier as shown the shaft-bearinglever M is of course in its downwardly swung position,

and means for limiting the downwardlyswinging of the lever are providedand comprise'an upright bolt Q pivoted at its lower end, as at Q, tothelever arallelly with'the fulcrum of the leverand etween the shaft andthe free end of the lever. The bolt Q extends from the lever M upwardlyloosely through the bracket-arm 12, and a thumbnut Q is mounted on thesaid bolt above the said arm, which thumb-nut forms a stop for,limitingdownward movement of the lever without interfering with thecapabilit of the lever to be swun u wardly. It wil be observed that theb a -carrier is adjusted vertically by manipulating the thumb-nut QObviously u on tightening the nuts R and R the bracket K is locked tothe furnacecasing, and consequently accidental lateral displacement ofthe said bracket is positively avoided. Withdrawal of the outer nut Rwhich is preferably in the form of a thumbnut, obviously renders thebracket K free to 4.5 be swung laterally and outwardly when theblank-carrier is elevated to the extent required to .raise theblank-holder I above the furnace. 1

'I would here remark that to avoid heating .50 of the hook-forming endsof the blank-hold ers I during the heating of the furnace preparatory tothe heating ofblanks in the furnace or at other times during theoperation of the furnace theblank-carrier is elevated out of anoperative position to remove the blank-holders upwardly from the heatingchamber of the furnace, and then by withdrawing the thumb-nut R theblank-carrier is swung laterally away from the furnace 0 after of coursedisengaging the pawl P from the engaging blank-holder.

It is of course obvious that in the opera tive position of theblank-barrier the vertical adjustment of the blank-holders I relative tothe heating chamber of the furnace is effected by the manipulation ofthe thumbnut Q and that the blank-carrier and consequently theblank-holders of the blankcarrier are properly adjusted laterally of theheating chamber of the fufnace by manipulating the thumb-nut R and nutR. a

By the construction and arrangement of parts hereinbefore described itwill be observed that the heating chamber 'B has its upper portion Bopen at the ends throu h 7 the medium of the slots 7) in the end wa lsof the said chamber to accommodate the passage of the blanks through thesaid portion of the said chamber; that the blankcarrier is normally freeto be elevated; that 30 the bracket R constitutes a laterally'movablesupport bearing the blank-carrier and arranged as required to render itcapable of shifting laterally away from the blank-heating means so thatobviously the blank-car- 5 rier, when it is elevated out of itsoperative osition to raise the blank-holders above the dank-heatingmeans When-rendered free to be thus shifted; that the bracket-arm 12 andbolt Rand nuts R and R constitute means for locking the said laterallyadjustal. Is support against displacement laterally in'the normal andoperative osition of the blank-carrier so that the blan -carrier issecured in the desired lateral adjustment-relative to the lrlank-heatingmeans in the normal and operative position of the blank-carrier; thatthe blank-ca'rrier-raising means formed by the lever M is borne bvthe'said laterally movable support; that the bolt Q,

bracket-arm 12 and nut Q constitute means for adjusting the lever andconsequently the blank-carrier vertically, and that the said adjustingmeans is borne by the said laterally movable su port.
